Why? Tell me!

There is no reason, because others may study hard without your knowledge. This is a way to learn well, and I hope it will be useful to you: first of all, you must get rid of unhealthy psychology, such as jealousy, but this is very difficult, especially for those who are very competitive. Good psychological quality is very important. Without a good attitude, even the best method is useless. You should be clear about your direction, otherwise no amount of efforts will be in vain. You should have your own opinions in learning, know yourself clearly, don't blindly follow, and don't be too unconventional. You know, learning is hard work, and you must bear any blow in the learning stage. Don't rely too much on others, but don't keep everything in your heart. It is often said that work and rest are combined, but few people can do it. When you really can't learn, it is necessary to be quiet or play. This is by no means a waste of time. Don't care too much about what others think of you. Even if you don't do well in the exam once, others sneer at you or stop believing in you, you must absolutely believe in yourself, otherwise you are a loser. It is common to listen carefully in class, but few people really do it. If you do it, it will work. If you didn't, you'd think it was nonsense. Some subjects need to do more questions, and there are appropriate sea tactics, such as mathematics, but some subjects are not like this, and some pay attention to accumulation and recitation. I mainly pay attention to the mentality, because this is very important. I must believe in myself at all times. Learning is for myself!
